Siemens 6ES7223-1BL32-0XB0 is a SIMATIC S7-1200 SM 1223 digital I/O module that expands a CPU’s I/O with 16 digital inputs and 16 transistor outputs. The 24 V DC inputs support sinking and sourcing configurations, while the 16 DO outputs are transistor-based, each rated up to 0.5 A. This SM 1223 module is designed for use with SIMATIC S7-1200 controllers to enable compact, scalable digital I/O for automation tasks such as line control, machine interfaces, and discrete control applications.
